On August 29, 1976, around 1:40 am, a fire erupted at 1138 Spruce Street in Chester, Pennsylvania. The building, in a row of two-family homes just south of the Delaware Expressway, burned for two hours, killing two boys: 13-year-old Brian Harvey and his 6-year-old brother, Derrick.

Neighbors spotted two local girls at the scene: 16-year-old Frances Newsome and 14-year-old Trina Garnett. But according to early reports in the Delaware County Daily Times, “the immediate focus” was Trina, a “mysterious girl” with a “grudge” against Sylvia Harvey, the boys’ mother. Investigators theorized that she had broken a kitchen window and climbed through, lighting matches throughout the first floor of the house and then escaping before it went up in flames. On September 3, Trina was arrested and charged with homicide, arson, conspiracy and burglary. She was held without bail; police told reporters she would be tried as an adult.
